民用被动式太阳房住宅大多数采用直接受益式和集热蓄热墙相结合的方式,而蓄热墙的效率会直接影响供暖和太阳能利用效率。下面我们通过热工分析对这个问题进行一些探讨。一、蓄热墙夹气层的厚度蓄热墙夹气层厚度S直接影响内部气体流动状况,进而影响对流换热的强弱。如果夹气层过厚,不仅建筑上不合理,造成浪费,更主要的是内部空气流
Most passive residential solar houses use a combination of direct-benefit and heat-collecting and heat-storing walls. The efficiency of the heat-retaining wall will directly affect heating and solar energy utilization efficiency. Here we discuss some of this issue through thermal analysis. 1. The thickness of the gas-jacketing layer on the heat-accumulating wall The thickness of the gas-jacketing layer on the heat-accumulating wall directly affects the internal gas flow conditions, which in turn affects the strength of convection heat transfer. If the gas-jacketing layer is too thick, not only is it unreasonable in construction, it causes waste, but more importantly, the internal air flow.
